Wrenches, I am curious if any of you solar thermal installers have had an anti-scald valve failure that left the end user with 100% untempered, hot water? We recently had a residential homeowner who purchased a Heliodyne system with Watts valve five or six years ago see a tempering valve fail in this manner. After a multi-week heat wave he had 160F water available throughout the home. Obviously not ideal.
I have always been under the impression anti-scalds would only fail 100% cold. Maybe this was a mixing valve sold as an anti-scald but it looks just like the Honeywell anti-scalds we install every day. I can't say I have had a ton of anti-scald failures but, of the handful we have had, I think all failed cold. Any thoughts are welcome.
